hi all
 
After executing the below sql query in c++, the printed results are:
 
WITH rnum AS (SELECT s.ISN, s.Date, ClosedPrice, row_number() OVER (partition BY s.ISN ORDER BY s.ISN, s.Date DESC) AS rownumber FROM SecurityData s INNER JOIN PortfolioHoldings p ON s.ISN = p.ISN   WHERE p.Pfid = 1876) SELECT DISTINCT ISN, Date, ClosedPrice FROM rnum WHERE rownumber <= 250))
 
//ID       Date            Price
US345 2014-08-17 342
US345 2014-08-16 310
...
FR123  2014-08-17  18.20
FR123 2014-08-16   15
 
Does anyone know how to build a price matrix for the IDs like:?
 
          |342  18.20|
MAT=|310   15    |
          |...       ...    |
 
Your feedback would be very appreciated
 
Cheers
